many a 后面加单数表示大量的

加单数

population是一个集合名词,它的用法有时较为特殊,所以很容易用错.下面谈一下它的用法.

一、population常与定冠词the连用,作主语用时,谓语动词常用第三人称单数形式.例如:

The world\'s population is increasing faster and faster.全世界的人口增长得越来越快.

At the beginning of the twentieth century,the world\'s population was about 1,700 million.在二十世纪初,全世界的人口大约是十七亿.

二、当主语是表示\"人口的百分之几、几分之几\"时,谓语动词用复数形式.例如:

About seventy percent of the population in China are farmers.中国大约有百分之七十的人口是农民.

三、有时population可用作可数名词,其前可用不定冠词.例如:

China has a population of about 1.3 billion.(=There is a population of about 1.3 billion in China.) 中国大约有十三亿人口.

New York is a big city with a population of over 10 million.纽约是一个有一千多万人口的大城市.

在表示多个地区的人口时,population要用复数形式populations.例如:

Many parts of the world,which once had large populations and produced plenty of crops,have become deserts.世界上很多地区一度人口众多,种植大量的农作物;现在,这些地区已经变成了沙漠.

四、表示人口的\"多\"或\"少\",不用\"much\"或\"little\",而要用\"large\"或\"small\".例如:

India has a large population.印度人口众多.

Singapore has a small population.新加坡人口少.

      eg .  We heard  the news  that  our team had won .

              He has  a problem  that  he doesn't  know  how  to get along well with others .
